          Abstract

          This study aimed to evaluate the weekday and weekend distribution of stroke case hospital admissions and their respective prognosis based on a sample from the Estudo de Mortalidade e Morbidade do Acidente Vascular Cerebral (EMMA), a cohort of stroke patients admitted to a community hospital in the city of São Paulo, Brazil. We ascertained all consecutive cases of first-time strokes between April 2006 and December 2008 and performed a subsequent one-year follow-up. No association was found between frequency of hospital admissions due to ischemic and hemorrhagic strokes and the specific day of the week on which the admission occurred. However, ten-day and twelve-month case-fatality was higher in hemorrhagic stroke patients admitted at the weekend. We also found that intracerebral hemorrhage patients admitted on weekends had a worse survival rate (50%) compared with those admitted during weekdays (25.6%, P log-rank = 0.03). We found a multivariate hazard ratio of 2.49 (95%CI: 1.10-5.81, P trend = 0.03) for risk of death at the weekend compared to weekdays for intracerebral hemorrhage cases. No difference in survival was observed with respect to the overall sample of stroke or ischemic stroke patients.

          El estudio evaluó la distribución de casos incidentes de accidente vascular cerebral (AVC) que fueron al hospital de lunes a viernes o durante los fines de semana en el Estudio de Mortalidad y Morbilidad del AVC (EMMA). El EMMA es una cohorte de pacientes con AVC en un hospital comunitario de la ciudad de São Paulo, Brasil. Casos consecutivos de primer episodio de AVC internados, entre abril de 2006 y diciembre de 2008, fueron seguidos prospectivamente durante un año. No hubo diferencia en la frecuencia de las internaciones por AVC isquémico o hemorrágico durante los días de la semana. Sin embargo, la letalidad en 10 días y tras un año había aumentado en el AVC hemorrágico. En el análisis de supervivencia de un año, pacientes admitidos los fines de semana por hemorragia intraparenquimatosa presentaron menor supervivencia (50%), comparados con los admitidos de Lunes hasta Viernes (22%, p log-rank = 0.03). Se encontró una razón de riesgo multivariada de un 2,49 (IC95%: 1,10-5,81; p tendencia = 0,03) de morir los fines de semana en comparación con los lunes y viernes para la hemorragia intracerebral. No hubo diferencia en la supervivencia para la muestra total de AVC ni para el AVC isquémico.

O EMMA é uma coorte de pacientes com AVC em hospital comunitário da cidade de São Paulo, Brasil. Casos consecutivos de primeiro episódio de AVC internados entre abril de 2006 e dezembro de 2008 foram seguidos prospectivamente por um ano. Não houve diferença na frequência das internações por AVC isquêmico ou hemorrágico pelos dias da semana. Entretanto, a letalidade em dez dias e após um ano estava aumentada no AVC hemorrágico. Na análise da sobrevida de um ano, pacientes admitidos nos finais de semana por hemorragia intraparenquimatosa apresentaram menor sobrevida (50%) quando comparados aos admitidos de 2ª a 6ª (22%) (p log-rank = 0.03). Encontrou-se uma razão de risco multivariada de 2,49 (IC95%: 1,10-5,81, p tendência = 0,03) de morrer nos fins de semana em comparação ao período de 2ª a 6ª feira para hemorragia intracerebral. Não houve diferença na sobrevida para amostra total de AVC nem para AVC isquêmico.

          Stroke incidence, prognosis, 30-day, and 1-year case fatality rates in Matão, Brazil: a population-based prospective study.

          Stroke is the main cause of death in Brazil and no prospective population-based study has been conducted in the country. The purpose of this study was to determine the incidence of stroke, stroke subtypes, case fatality, and prognosis after 1 year of follow-up in the city of Matão, Brazil. Using overlapping methods of case ascertainment, all stroke cases that occurred in the city of Matão (population, 75,053) from November 1, 2003 to October 31, 2004 were followed-up at 1 month and 1 year after the episode. Standard criteria for population-based stroke studies were followed. Of 141 suspect stroke cases identified, 81 were first-ever-in-a-lifetime strokes. All patients underwent a CT scan. The crude annual incidence rate per 100,000 per year was 108 (95% CI, 85.7-134.1) and the rate adjusted for sex and age to the Segi population was 137 (95% CI, 112.0 to 166.4) per 100,000 inhabitants per year. Ischemic stroke occurred in 69 (85.2%) subjects, intracerebral hemorrhage in 11 (13.6%), and subarachnoid hemorrhage in 1 (1.2%). The 30-day case fatality rate was 18.5 and the 1-year case fatality rate was 30.9%. After 1 year of follow-up, 43% of the patients were independent in activities of daily living, 49.4% had independent gait, and 15.9% had a recurrent stroke. The present results are similar to those obtained in other stroke population-based studies. Future studies in Matão will provide the opportunity to discover ways to decrease the stroke burden in Brazil.

              Mortality among patients admitted to intensive care units during weekday day shifts compared with "off" hours.

              To determine whether mortality rates among intensive care unit (ICU) patients differ according to the time of ICU admission, we compared the death rates for patients admitted during weekday day shifts and off hours (from 6:30 pm to 8:29 am the next day for night shifts, from Saturday 1:00 pm to Monday 8:29 am for weekends, and from 8:30 am to 8:29 am the following morning for public holidays). Retrospective cohort study of data collected prospectively from 23 ICUs located in the Paris metropolitan region, France. Between January 2000 and December 2003, 51,643 patients were admitted to these ICUs. Patients were grouped according to their day and time of admission and compared using univariable and multivariable analyses. None. Of the 51,643 patients admitted to ICUs, 33,857 (65.6%) were admitted during off hours. These latter patients were less critically ill than those admitted during day shifts, had fewer failed organs, required fewer support procedures, and their crude in-hospital mortality was lower (20.7 vs. 24.5%, p < .0001). After adjustment for initial disease severity, in-hospital mortality was not higher for off-hours admissions than weekday day admissions and even remained slightly lower (adjusted odds ratio, 0.93; 95% confidence interval, 0.87-0.98). Admission during off hours is common. In our ICUs, off-hours admissions were not associated with higher mortality and might even be associated with a lower death rate.
